[To the process of registration of ageing process (author's transl)]. 1978

A Pfeiffer

A cybernetical scheme and a corresponding system of differential equations, describing the dehydration and the diminishing metabolism rate of the aging cell as well as of the whole of the organism, are generalised to adapt them also to other phenomena of aging. The resulting expressions are tested by comparison with a number of representative theoretical and experimental dates of various aging processes.
